🏎 Performance enhancement at scale

React hook from is getting a general performance upgrade and enhancement. The following API will get big performance improvement at scale, which means it may not improve on small or medium-size applications, but rather large and complex applications with subscriptions.

• useWatch
• useFieldArray
• watch
• getValues

Result Env: dev build + throttle 4x CPU + Chrome + MAC M1

📦 Package size-reduction

• 5% package size reduction with compress and gzip

Total Size: 30.3 kB

🔫 Trigger

• Trigger will enable object name trigger and field array name trigger

useFieldArray({ name: 'test' })

trigger('name') // will trigger the whole field array to validate

📑 register

• added a disabled prop as an option to toggle input disable attribute
• register will be able to seek input DOM reference through the ref callback

register('test', { disabled: true }) // will set value to undeinfed and pass disabled down to the input attribute

<div {...register('test')}>
  <input name="test" /> // this input will be registered
</div>

👀 useWatch

• added disabled prop to toggle the state subscription.

useWatch({ disabled: true }) // you toggle the subscription

⌨️ useFormState

• added disabled prop to toggle the state subscription.

useFormState({ disabled: true }) // you toggle the subscription

⛳️ setValue

• allow set value for non-registered inputs include nested object and array field.

<input {...register('test.0.firstName')} />

setValue('test', [{ firstName: 'bill' }, {firstName: 'kotaro}, {firstName: 'joris'}]) // this will works
